Because of Winn-Dixie

Ten-year-old India Opal Buloni has just moved to the fictional small town of Naomi, Florida with her father who is a preacher.

While at Winn-Dixie, Opal encounters a scruffy Berger Picard that is wreaking havoc. She (not wanting the manager to send him to the pound) claims that he is her dog and names him "Winn-Dixie". He becomes friends with everyone he encounters, and so Opal makes some new friends in the process. She also rekindles her relationship with her father and learns ten things about her mother, Benjean-Megan, who abandoned them when she was three. She describes the preacher as a turtle, always sticking his head into his shell, and never wanting to come out into the real world. This is most likely because of how sad he is about her mother, whom he is still in love with.
